Here's The CW's official description for "The Devil and Sam Oliver," the May 26 season 2 finale episode of Reaper!

SAM TAKES ON THE DEVIL — Sam (Bret Harrison) and Andi (Missy Peregrym) try to find Tony (guest star Ken Marino) to help them translate the scroll Nina (Jenny Wade) brought back from Hell. Sam discovers that he can summon The Devil (Ray Wise) with a specific incantation that will trap him into a competition. Sam challenges The Devil to a game of quarters, but they play to a draw and The Devil refuses a rematch, so Andi offers her soul as collateral. Tyler Labine and Rick Gonzalez also star. Kevin Dowling directed the episode written by Michael Daley (#214).
